INERTIA-OPERATED CLIMBING TOY Filed May 24, 1947 2 ZlNVEETO-R A Z Z/W $4ATTORNEY rod, the second of said loops having its efiective diameter andaxial length so correlated with the rod diameter that the loop binds onthe rod when tilted axially, a freely vibrating resilient memberconnected to the same part as the second of said loops in position tomove back and forth in directions that transmit tilting force to thesecond of said loops and by such coaction alternately binding andreleasing the second of said loops on the rod, and means to=limit therelative movement between said parts in one direction.

3. A toy comprising, a rod, a climbing figure consisting of tworelatively movable parts, each i of said parts including a loop looselyencircling said rod, a freely vibrating resilient member connected toone of said parts, and movable in direcv tions to shift one of the loopsalternately between v a position in which it is tilted with' respect tothe axis of the rod and another position in which the.

loop is near enough to alignment with the rod to slide freely on saidrod and a weight attached to said resilient member toincrease theinertia and .slow the normal period of vibration thereof.

4. A toy comprising, a rod, a climbing figure consisting of tworelatively movable parts, each of said parts including a loop looselyencircling said resilient member to increase the inertia and slow thenormal period of vibration thereof, and means to limit the relativemovement between said parts in one direction. V

5. A toy comprising, a rod, a part constituting the torso, head and armsof a toy figure, a loop connected to said arms and loosely encirclingsaid rod, a second partconstituting the legs of said figure, a loopconnected to said legs and loosely encircling said rod, said loop havingits effective diameter and axial length so correlated with the roddiameter that the loop binds on the rod when tilted axially, a pivotalconnection between said parts, and a freely vibrating resilient memberconnected to said second part and adapted, when vibrating, to causerelative movement between said parts and to move said second partalternately to positions to cause its loop to bind on and free itselffrom said rod.

6. A toy comprising, a rod, a part constituting the torso, head and armsof a toy figure, a loop 4. connected to said arms and loosely encirclingsaid rod, a second part constituting the legs of said figure, a loopconnected to said legs and loosely encircling said rod, said loop havingits effective diameter and axial length so correlated with the roddiameter that the loop binds on the rod when tilted axially, a pivotalconnection between said parts, a freely vibrating resilient memberconnected to said second part and adapted, when vibrating,- to causerelative movement between --said parts and'to move said second partalternately to positions to cause its loop to bind on :and free itselffrom said rod, and means to limit direction which causes said last namedloop to free itself from said rod.

7. A toy including, in combination, a straight rod,a cli'mbingfi'gurehaving one part constituting a torso, head and arms, and an element atthe outer ends of the arms extending around the rod and connecting saidupper part to the rod, said figure having a lower partconstituting itslegs, a pivot at one end of the second part connecting the second partto the first part, an elementat the other end of the second partextending around the rodand having its width and axial length correlatedwith the cross section of the rod so as to bind on the rod when tiltingaxially with respect to the rod, a resilient member extending from thesecond part of the figure in a direction away from the rod and beyondthe pivot, a weight attached to the resilient member for increasing itsinertia and reducing its period of vibration, and means for limitingrelative movement between the parts, said means including an abutment onthe second part radially spaced from the pivot and in position tostrikev against the first part when the second part is swung about thepivot by upward movement of the weight about the pivot.
